Hi HN, I built DropMind because I wanted a very simple self-hosted way to quickly send notes, links and files to myself across devices. Originally I was using dmyst, but I wanted something I could fully self-host and keep extremely lightweight. The idea is to have a personal “memory cache”: a place where you can quickly drop something (text, link, screenshot, file) and retrieve it later from another device. It runs with Docker, uses a FastAPI backend and a PWA frontend so it works well on mobile too. Recently I added Android share support, and I'm experimenting with improving offline capabilities. Curious to hear how people here would use something like this.
